Resumo

Bee pollen has been promoted as a dietary supplement for humans due to its nutritional and bioactive properties. Sixty-two samples of Apis mellifera dehydrated bee pollen collected in Brazil (eight states and Federal District) were analyzed for phenolic compounds, flavonoids, antioxidant activity using DPPH, beta-carotene and ORAC methods, and antimicrobial activity. The values obtained for total phenolic compounds ranged from 12.60 to 84.22 mg GAE/g bee pollen while total flavonoids oscillated between 1.90 and 36.85 mg quercetin/g bee pollen. The IC50 ranged from 0.35 to 13.42 mg bee pollen/mL of extract. The inhibition percentages ranged from 52.58 to 98.37% of bee pollen extract using the beta-carotene method. When measured by the ORAC method, antioxidant activity was between 132.98 and 575.85 mu mols eq. Trolox/g bee pollen. Bee pollen efficiently inhibited the growth of all the microorganisms studied. Candida albicans was the most resistant, while Staphylococcus epidermides was the most sensitive. (AU)
